PLS CAD — Transmission Line Design
PLS-CADD transmission line modeling, sag-tension, and tower spotting.
MapSphere delivers PLS-CADD transmission line design and modeling — terrain integration, sag-tension analysis, tower spotting, and clearance verification for power and transmission corridors.
From LiDAR-derived terrain to optimized tower placement, our PLS-CADD workflows support reliable, standards-compliant transmission line design, clearance checks, and as-built line modeling.

PLS CAD — common questions
01What does a PLS-CADD transmission line deliverable include?
A typical package includes the PLS-CADD model, sag-tension analysis, tower spotting and optimization, clearance/ground-check reports, and plan-and-profile drawings — built on LiDAR-derived terrain for real-world accuracy.
02How does LiDAR feed PLS-CADD design?
Classified LiDAR gives a precise bare-earth terrain plus existing conductors, structures, and vegetation. We import that into PLS-CADD so tower placement, clearances, and sag-tension are calculated against the actual corridor rather than coarse contours.
03Can you verify clearances on an existing line?
Yes — using as-built LiDAR we model the existing line, check statutory ground and crossing clearances, and flag encroachments or hot-spots for remediation.
